My invention is a. hose coupling tool for attaching wire to a hose to clamp the hose securely to the coupling.

An object of my invention is the construc- 6 tion of a tool for drawing or clamping wire to 'a hose to secure same to coupling, and embodies an implement for bending a straight piece of wire forming a pair of eyes and a species of loop. The double ends of the wire are then passed around the hose through the eyes and engaged by my implement to draw the ends tight. In order to effect this, I have a base with a pair of holes therethrough, through which the two ends of the wire may extend upwardly, and rotatably mounted on the base there is a jack screw which has a handle attached thereto. Fitted on the jack screw there is a clamping holder with a pair of perforations therethrough and set screws to engage the free ends of the wire. Hence, on rotation of the handle the jack screw being rotated, separates the clamp on the base, thus pulling tight on the wire until the hose is' attached sutliciently tight to the coupling, and after this the tool may be turned to one side, there being a sharp bend or crimp in the wire adjacent the eyes.

Another object of my invention comprises 30 a construction of the tool in which the base provides a mounting for a pair of slidable chisels which may be struck by a hammer and sever the wire adjacent the bend. These severed ends may then be hammered tight against the rubber hose and the wired coupling is completed.

y invention is illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of my hose coupling tool with the connection partly completed, and also illustrating ra completed joint.

Fig. 2 is a vertical section on the line 2-2 of Figure 1 in the direction of the arrows.

Fig. 3 is a perspective view ofthe tool.

Fig. 4 is a diagram of part of the tool showing the manner of bending thewire to form the two eyes and a loop.

Referring first to the manner of making the loop. This is effected by utilizing the handle 11 of the tool, which has apair -of pins 12 extending upwardly therefrom. Thewire to form the binding or tie for the coupling is preferably formed of a straight 55 section in which one part 13 is placed against the pins 12 and parallel to the handle 11. The wire is then given a twist or bent around the pins forming a pair of eyes 14 with the wire portion 15 passing over the part 13. The wire so bent is so removed from the pins 12, and the port-ions 16 of the wire may then be bent around a hose and the ends 17 pass through the eyes 14. The further details of securing the wire to the'hose is substantially as hereunder given.

The tightening features of the tool comprise a base 18 which is preferably a rectangular block and has a pair of openings o1' apertures 19 extending therethrou h, and it is through these apertures that t e ends 17 of the wire are inserted. Secured to the base there is a jack screw 20 which preferably has a head'21 fitted in a socket in the base, retained therein by a set screw 22. With this construction the jack screw is free to rotate relative to the block, and may be manipulated by the handle 11.

The wire clamp 23 comprises a rectangular block-like structure 24 with a pair of apertures 25 therethrough, and set screws 26 are threaded in the ends lof the block. When the wire is passed upwardly through the apertures 25, the set screws may be jammed against the free ends of the wire and then the handle is rotated, which separates the base and the clamping part of the tool, this action putting a tensile Stress on the wire and pulling it tight in engagement with the hose and a coupling designated bythe numeral 27.

When the wire is tightened to a sufficient extent, the implement is turned to one side in the direction of the arrow 28 as shown in Figure 2, which gives a sharp angular -bend in the wire adjacent the eyes 14. The Wire is then severed in the following manner.

A pair of cold chisels 29 are slidably mounted in bores 30 in the base 18. Each chisel has a head 31 which is engaged by a compression spring 32 fitted in an enlargement of the bore, thus normally tending to maintain the chisel in its outward position, and each of the chisels is restricted in its movement by a stop screw 33 which is threaded through the top of the block forming the base and engages in an elongated notch 34 in each of the chisels. After the wire has been bent to one side in the manner described, the heads 31 of the chisels may be struck by a hammer thus severing the ywire held in the clamp 23 from the wire loop around the hose. The ends 35 of the wire forming the loop are then hammered into the hose and preferably hammered close to the portion of the wire 16 which encircles'the hose.

From the above description it will be seen that I have developed acomprehensive hose coupling tool which may be utilized to bend the wire into shape suitable for usel as a hose clamp in connection with the coupling, and that the implement is arranged to draw tight-ly on the Wire, thus forming a tight connection bet-Ween the coupling and the hose, and then subsequently to sever the wire after bending in proper position for finally Securing it in position.

Various' changes may be made in the prin-- ciples of my invention without departing from the spirit thereof, as set forthin the description, drawings and claims. n

I claim :v -v

1. A hose coupling tool having a block forming a base with an opening vertically therethrough, a jack mounted on the base, a clamp on the jack to engage a wire extending through the opening in the base, means to operate the jack to separate the base and the clamp and exert a tension on the Wire, the

base having a bore at right angles to the said opening..and a cold chisel operating in said bore adapted to sever `the wire fastened through the opening in the base.

2. A hose coupling tool comprising in combination a block forming a base with a vertical aperture therethrough, a screw jack rotatably mounted on the base and extending vertically upwardly, a clamp threaded on the screw jack land having means to engage a wire passed upwardly through the aperture in the base, the jack' on rotation separating the base and the clamp and exerting a tension on the wire, the jack and base being tiltable to one side to form a bend in the wire below the base, the said base having a lateral bore, a cold chisel slidably mounted therein, a. spring normally thrusting the cold chisel outwardl and means to retain the cold chisel in tie bore, the said cold chisel being adapted to cut a wire extending through the aperture in the base.

3. A hose coupling tool comprising in combination a rectangular block forming a base and having a plurality of vertical openings therethrough, a screw jack having its lower end rotatably mounted in the base between the said apertures, a clamp threaded on the screw jack having a pair of apertures therethrough, set screws in the clamp to engage wires in the apertures of the clamp, such wires being passed upwardly through the apertures in the base, a handle to rotate a screw jack and separate the base and the clamp, thereby exerting a tension on the Wire, the base and the jack being tiltable to form la bend in the wire, and a pair of cold chisels slidable in bores at right angles to the openings therethrough, each of .said cold chisels being adapted to sever a wire in one of said openings.

In testimony whereof I have signed my name to this specification.
